BACKGROUND OF THE INVENTION

The present invention relates to novel substituted hexahydroazepinones and tetrahydrobenzazepinones, pharmaceutical compositions comprising such compounds and the use of such compounds in the treatment and prevention of central nervous system and gastrointestinal disorders. The pharmaceutically active compounds of this invention are selective CCK-B receptor antagonists.

Cholecystokinin (CCK) is a 33-amino acid peptide originally discovered and characterized in 1971. (See Mutt et al., Biochem. J., 125, 57 (1971)). It carries out its biological responses by binding to its two receptor types: CCK-A and CCK-B. The CCK-A receptor is located primarily in the gallbladder and pancreas, and mediates CCK-induced enzyme secretion and gallbladder contraction during a meal. The CCK-B receptor is located in the stomach, where it is involved in acid secretion, and in the brain, where it mediates pain and anxiety responses.

A number of potent and selective non-peptide antagonists for these two receptors are known (See M. G. Bock, Drugs of the Future, 16 (7), 631-640 (1991) and R. M. Freidinger, Med. Res. Rev., 9, 271-290 (1989)). Merck's L-364,718 (devazepide) is a selective CCK-A antagonist. (See O'Neill et al., Brain Res., 534, 287-290 (1990)). This compound, however, has proven not to be clinically useful. Merck's benzodiazepine L-365,260 is a selective CCK-B antagonist that was found to have an analgesic effect on squirrel monkeys. (See O'Neill et al., Brain Res., 534, 287-290 (1990)). Clarke-Davis' CI-988 is a selective CCK-B antagonist that was found to reverse the pentagastrin-induced anxiogenic response in rats. (See Singh et al., Proc. Nat'l. Acad. Sci., U.S., 88, 1130-33 (1991)).

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

The compounds of the formulae I and II may be prepared as described in the following reaction schemes and discussion. Unless otherwise indicated, R¹, R², R³, R⁴, R⁵, R⁶, Y¹, Y², Z¹, Z², W¹ and W² in the reaction schemes and discussion that follow are defined as above. ##STR4##

The preparation of compounds of the formula I wherein R¹ is CO₂ R², C₆ H₅, CONR⁴ R⁵ or SO₂ NR³ R⁶ (hereinafter referred to as compounds of the formula IA) is illustrated in scheme 1.

Referring to scheme 1, a compound of the formula III is reacted with hydroxylamine hydrochloride in methanol in the presence of sodium bicarbonate or triethylamine, to form a compound of the formula IV. This reaction is generally carried out at a temperature from about room temperature to about the reflux temperature of the reaction mixture. The compound of formula IV so formed is then converted to a compound of the formula V by reacting it with tosyl chloride in pyridine at about 0° C. for about 24 hours.

Alternatively, compounds of the formula III may be converted directly into the corresponding compounds having formula V in a one step procedure. According to this procedure, a compound of the formula III is reacted with NH₂ OSO₃ H (hydroxylamine --O-- sulfonic acid) in formic acid at about the reflux temperature of the reaction mixture. This one step procedure is preferred over the two step procedure described above for all compounds of the formula IV except those wherein Y¹ is phenyl and adjacent to the oxo group.

Bromination of the compound of formula V yields the corresponding compound having formula VI. The bromination is typically carried out by first adding a compound of the formula V to a mixture of phosphorus pentachloride and pyridine in methylene chloride at about 0° C. Then, phenyltrimethylammonium bromide tribromide is added to the reaction mixture, also at a temperature of about 0° C. Alternatively, the second step, which involves the addition of the brominating agent, may be replaced by a procedure in which bromine is added at a temperature of about 0° C. and allowed to react for a period of about 0.5 hours to about 5 hours, preferably about 2 hours, resulting in dibromination of the saturated nitrogen containing seven membered ring. One of the bromine atoms is then selectively removed by treatment with hydrogen gas in the presence of palladium which has been poisoned with quinoline.

The brominated compound of formula VI is then alkylated at the ring nitrogen by reaction with a compound of the formula XCH₂ R¹, wherein X is bromine when R¹ is phenyl and X is iodine for all other R¹, in tetrahydrofuran (THF) in the presence of sodium hydride. This reaction, which yields the corresponding compound of formula VII, is usually conducted at a temperature from about room temperature to about 150° C. It is preferably conducted at the reflux temperature of the reaction mixture.

The compound of formula VII formed in the above step is then reacted with an alkali metal azide to produce a compound of the formula VIII. The preferred reactant is sodium azide. Generally, this reaction is carried out in a reaction inert solvent such as dimethylformamide (DMF) or dimethylsulfoxide (DMSO), preferably DMF, at a temperature from about 60° C. to about 100° C., preferably about 80° C.

Reduction of the azide of formula VIII yields the corresponding amine of formula IX. The reduction is typically accomplished using hydrogen gas at a pressure of from about 1 to about 3 atmospheres in the presence of palladium on carbon (Pd/C). Suitable reaction inert solvents include halogenated hydrocarbons and (C₁ -C₆) alkanols. Ethanol is the preferred solvent. The reaction temperature may range from about 15° C. to about 70° C., with about room temperature being preferred.

Alternatively, the reduction may be accomplished using a trialkyl or triaryl phosphine. Examples of appropriate reactants are triphenylphosphine and tributylphosphine. This reaction is generally conducted in a reaction inert solvent such as THF or another ethereal water miscible solvent in the presence of water, at a temperature from about room temperature to about 100° C. Preferably, it is conducted in THF at about room temperature.

The compound of formula IX so formed is then converted into the corresponding compound having formula IA by reacting it with an isocyanate of the formula C⁶ H₄ Z¹ Z² NCO. Appropriate reaction inert solvents for this reaction include hydrocarbons such as hexane, benzene and toluene, halogenated hydrocarbons such as methylene chloride and 1,2-dichloroethane, ethereal solvents such as ethyl ether, THF and glyme, and pyridine. The preferred solvent is 1,2-dichloroethane or methylene chloride. Tertiary organic amines may be useful as catalysts. The reaction temperature may range from about 0° C. to about 150° C. The reflux temperature is preferred.

The isocyanate of the formula C₆ H₄ Z¹ Z² NCO used in the foregoing reaction can be formed by procedures well known to those skilled in the art. One such method involves mixing a benzoic acid derivative with diphenylphosphorylazide, or an analagous reagent, in the presence of an organic base such as a trialkylamine, preferably triethylamine or diisopropylethylamine. This reaction is usually conducted in an ethereal, hydrocarbon or chlorinated hydrocarbon solvent, preferably tetrahydrofuran or benzene, at a temperature from about room temperature to about 100° C., preferably at the reflux temperature of the solvent, for a period from about 20 minutes to about 24 hours, preferably about 1 hour.

Scheme 2 illustrates the synthesis of compounds of the formula I wherein R¹ is CO₂ H (hereinafter referred to as compounds of the formula IB) from compounds of the formula IA wherein R¹ is CO₂ R². It also illustrates a method of preparing compounds of the formula IA wherein R is an amide (i.e., R¹ is CONR₄ R⁵) from the corresponding acids of formula IB.

Referring to scheme 2, hydrolysis of a compound of the formula IA wherein R¹ is CO₂ R² yields the corresponding acid of formula IB. The hydrolysis is typically carried out using trifluoroacetic acid in a reaction inert solvent as hexane, an ethereal solvent (e.g., ethyl ether or THF) or a halogenated hydrocarbon solvent (e.g., methylene chloride or 1,2-dichloroethane), at a temperature from about -78° C. to about 50° C. It is preferably carried out using trifluoroacetic acid in a halogenated hydrocarbon cosolvent at about 0° C.

The acid of formula IB may be converted into the corresponding amide of formula IA, wherein R¹ is CONR⁴ R⁵, by reacting the acid with an amine of the formula NHR⁴ R⁵ in the presence of a dehydrating agent. The dehydrating agent is preferably a carbodiimide. Other dehydrating agents that may be used are 1,1'-carbonyldiimidazole and isobutylchloroformate/N-methylmorpholine. This reaction is generally conducted in a reaction inert solvent selected from hydrocarbons such as benzene, toluene and hexane, halogenated hydrocarbons such as methylene chloride and 1,2-dichloroethane, ethereal solvents such as ethyl ether, THF and glyme, and pyridine, preferably THF, at a temperature from about 0° C. to about 120° C., preferably at about room temperature.

Scheme 3 illustrates the preparation of compounds of the formula II wherein R¹ is CO₂ R², C₆ H₅, CONR⁴ R⁵, or SO₂ NR³ R⁶ (hereinafter referred to as compounds of the formula IIA).

Referring to scheme 3, a compound of the formula X is converted into the corresponding compound of formula XII by the following two step procedure. First, the compound of formula X is converted into an oxime by the method described above and illustrated in scheme 1 for forming compounds of the formula IV from compounds of the formula III. Then, rearrangement of the oxime to form the lactam having formula XI is accomplished by reacting the oxime with polyphosphoric acid. This reaction may be carried out at temperatures ranging from about room temperature to about 200° C. Preferably, the reaction mixture is heated to about 160° C.

The resulting compound of formula XI is then brominated to form a compound of the formula XII by first reacting it with phosphorous pentachloride and pyridine, and then adding bromine. The reaction with phosphorus pentachloride and pyridine is conducted as described above for the first step in the bromination of compounds of the formula V. The reaction with bromine, which results in monobromination, is carried out at a temperature from about -78° C. about 0° C., preferably at about -40° C.

Alkylation of the compound of formula XII yields the corresponding compound of formula XIII. The alkylation is carried out by reacting the compound of formula XII with a compound of the formula XCH₂ R¹, wherein X is bromine when R¹ is phenyl and X is iodine for all other R¹, in THF/DMSO in the presence of lithium dialkylamide. It is preferable to add the DMSO cosolvent after adding the lithium dialkylamide. The reaction temperature may range from about -78° C. to about 0° C. during addition of the base, and is preferably about -78° C. The reaction is slowly warmed to a temperature from about -20° C. to about 50° C. when the DMSO is added. Preferably, the reaction is warmed to about room temperature during addition of DMSO.

The conversion of compounds of the formula XIII formed by the foregoing procedure into the corresponding compounds of the formula IIA by the reaction sequence XIII→XIV→XV→IIA depicted in scheme 3 in carried out by the method described above for the analogous reaction steps VII→VIII→IX→IA depicted in scheme 1.

Compounds of the formula II wherein R¹ is CO₂ H may be prepared, and compounds of the formula II wherein R¹ is CONR⁴ R⁵ may be prepared, alternatively, by the procedure depicted in scheme 2 and described above forming the analogous compounds of formula I.

The starting materials used in the procedures of schemes 1 and 3 are either commercially available, known in the art or readily obtainable form known compounds by methods that will be apparent to those skilled in the art.

The preparation of other compounds of the formulae I and II not specifically described in the foregoing experimental section can be accomplished using combinations of the reactions described above that will be apparent to those skilled in the art.

In each of the reactions discussed or illustrated in schemes 1 to 3 above, pressure is not critical unless otherwise indicated. Pressures from about 0.5 atmospheres to about 5 atmospheres are generally acceptable, and ambient pressure, i.e. about 1 atmosphere, is preferred as a matter of convenience.

The compounds of the formulae I and II (the active compounds of this invention)which are basic in nature are capable of forming a wide variety of different salts with various inorganic and organic acids. Although such salts must be pharmaceutically acceptable for administration to animals, it is often desirable in practice to initially isolate a compound of the formula I or II from the reaction mixture as a pharmaceutically unacceptable salt and then simply convert the latter back to the free base compound by treatment with an alkaline reagent and subsequently convert the latter free base to a pharmaceutically acceptable acid addition salt. The acid addition salts of the active base compounds of this invention are readily prepared by treating the base compound with a substantially equivalent amount of the chosen mineral or organic acid in an aqueous solvent medium or in a suitable organic solvent, such as methanol or ethanol. Upon careful evaporation of the solvent, the desired solid salt is readily obtained.

The active compounds of this invention and their pharmaceutically acceptable salts are useful as selective CCK-B receptor antagonists, i.e., they possess the ability to antagonize the effects of CCK at its B receptor site in mammals, and therefore they are able to function as therapeutic agents in the treatment of the aforementioned disorders and diseases in an afflicted mammal.

The active compounds of this invention and their pharmaceutically acceptable salts can be administered via either the oral, parenteral or topical routes. In general, these compounds are most desirably administered in dosages ranging from about 5.0 mg up to about 1500 mg per day, although variations will necessarily occur depending upon the weight and condition of the subject being treated and the particular route of administration chosen. However, a dosage level that is in the range of about 0.07 mg to about 21 mg per kg of body weight per day is most desirably employed. Variations may nevertheless occur depending upon the species of animal being treated and its individual response to said medicament, as well as on the type of pharmaceutical formulation chosen and the time period and interval at which such administration is carried out. In some instances, dosage levels below the lower limit of the aforesaid range may be more than adequate, while in other cases still larger doses may be employed without causing any harmful side effect, provided that such larger doses are first divided into several small doses for administration throughout the day.

The active compounds of the invention may be administered alone or in combination with pharmaceutically acceptable carriers or diluents by either of the three routes previously indicated, and such administration may be carried out in single or multiple doses. More particularly, the novel therapeutic agents of this invention can be administered in a wide variety of different dosage forms, i.e., they may be combined with various pharmaceutically acceptable inert carriers in the form of tablets, capsules, lozenges, troches, hard candies, powders, sprays, creams, salves, suppositories, jellies, gels, pastes, lotions, ointments, aqueous suspensions, injectable solutions, elixirs, syrups, and the like. Such carriers include solid diluents or fillers, sterile aqueous media and various non-toxic organic solvents, etc. Moreover, oral pharmaceutical compositions can be suitably sweetened and/or flavored. In general, the therapeutically-effective compounds of this invention are present in such dosage forms at concentration levels ranging from about 5.0% to about 70% by weight.

For oral administration, tablets containing various excipients such as microcrystalline cellulose, sodium citrate, calcium carbonate, dicalcium phosphate and glycine may be employed along with various disintegrants such as starch (and preferably corn, potato or tapioca starch), alginic acid and certain complex silicates, together with granulation binders like polyvinylpyrrolidone, sucrose, gelatin and acacia. Additionally, lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc are often very useful for tabletting purposes. Solid compositions of a similar type may also be employed as fillers in gelatin capsules; preferred materials in this connection also include lactose or milk sugar as well as high molecular weight polyethylene glycols. When aqueous suspensions and/or elixirs are desired for oral administration, the active ingredient may be combined with various sweetening or flavoring agents, coloring matter or dyes, and, if so desired, emulsifying and/or suspending agents as well, together with such diluents as water, ethanol, propylene glycol, glycerin and various like combinations thereof.

For parenteral administration, solutions of an active compound of the present invention in either sesame or peanut oil or in aqueous propylene glycol may be employed. The aqueous solutions should be suitably buffered (preferably pH greater than 8) if necessary and the liquid diluent first rendered isotonic. These aqueous solutions are suitable for intravenous injection purposes. The oily solutions are suitable for intraarticular, intramuscular and subcutaneous injection purposes. The preparation of all these solutions under sterile conditions is readily accomplished by standard pharmaceutical techniques well known to those skilled in the art.

Additionally, it is also possible to administer the active compounds of the present invention topically when treating inflammatory conditions of the skin and this may preferably be done by way of creams, jellies, gels, pastes, ointments and the like, in accordance with standard pharmaceutical practice.

The activity of the compounds of the present invention as CCK-B antagonists may be determined by an assay that measures their ability to inhibit the binding of 125-I-BH-CCK-8 to the CCK-B receptor in a guinea pig cortical membrane preparation. This procedure is carried out as follows. The cortex is dissected from one male Hartley Guinea pig and homogenized (15 strokes) with a teflon homogenizer in 20 volumes (w./v.) of the assay buffer, which consists of 50 mM Tris (i.e., trimethamine, which is 2-amino-2-hydroxymethyl-1,3-propanediol)hydrochloric acid having pH 7.4 and 5 mM of manganese chloride at 4° C. The homogenate is centrifuged at 4° C. for 30 minutes at 100,000×G. The pellet is resuspended in the same buffer and spun as described above. The final pellet is diluted to a concentration of 20 mg/ml with the assay buffer for use in the binding assay. The tissue is kept on ice at all times.

An incubation mixture is prepared, which consists of 50 uL of the tissue preparation, prepared as described above, 100 uL 125-I-BH-CCK-8 (to give a concentration of 50 pM in the final assay), 20 uL of a blank or the compound being tested, and 30 uL of Tris with 4% DMSO. All drugs and dilutions are made using 4% DMSO in the assay buffer yielding a final assay DMSO concentration of 1%.

The reaction is initiated with the addition of tissue to a 96-well plate containing 125-I-BH-CCK-8 and the appropriate blank or compound being tested. Non-specific binding is estimated using 1 uM sulphated CCK-8. The reaction is terminated by spinning the plates in a H1000B rotor fitted on a Sorvall RT6000 refrigerated centrifuge at 4° C. The supernatant is discarded, and the pellets washed with 200uL of assay buffer, and the plate is spun as above. The supernatant is decanted again, and the pellet is harvested onto Betaplate filters (which have been soaked in 0.2% polyethyleneimine for a minimum of 2 hours) using a Skatron cell harvester at setting 222 using Tris HCl pH 7.4 as the wash buffer. The filtermats are counted on a Betaplate counter for 45 seconds per sample.

Data are expressed as IC₅₀ values (the concentration which inhibits 50% of the specific binding of 125-I-BH-CCK-8). The data is analyzed using non-linear regression analysis.

The present invention is illustrated by the following examples. It will be understood, however, that the invention is not limited to the specific details of these examples.

EXAMPLE 1 N-tert-butyl-2-[3-(3-(3-tolyl)ureido)-2-oxo-5-phenyl-2,3,4,5-tetrahydro-1H-(1)benzazepin-1-yl] ethanoic acid amide

A. 3-Bromo-5-phenyl-2,3,4,5-tetrahydro-1H-(1)benzazepin-2-one

To a 125 ml round-bottomed flask containing PCl₅ (1.041 g, 5 mmoles) dissolved in 50 ml methylene chloride under nitrogen in an ice/acetone bath was added 5-phenyl-2,3,4,5-tetrahydro-1H-(1)benzazepin-2-one (1,187 g, 5 mmoles). A slight temperature rise was noted, and then pyridine (0.42 ml, 5.25 mmoles)in 5 ml methylene chloride was added rapidly dropwise. The mixture was stirred for 15 minutes. and then cooled to -45° C.. Bromine (0.258 ml, 5 mmoles) in 7 ml methylene chloride was then added dropwise over 30 minutes. with rapid stirring. The bath was removed after 15 minutes. and the mixture was allowed to come to room temperature. Thin layer chromatography (TLC) (silica gel, 23:2, methylene chloride:ethyl acetate) showed no starting material, only a non-polar intermediate (iminochloride). The remainder of the reaction was diluted with an equal volume of tetrahydrofuran and 200 ml water added. This mixture was stirred for 40 minutes, then separated. The aqueous layer was re-extracted with methylene chloride and the combined organic fractions washed with water, dried with brine and sodium sulfate, filtered, and evaporated yielding 1.56 g (98.7%) of crude product.

The diastereomeric bromides (R_(f) =0.57, and 0.48) may be separated by chromatography or crystallized from ether and hexane; however, the mixture was used directly in the next step (B).

The solid obtained by crystallization was predominately the more polar isomer while the mother liquor contained more of the less polar isomer as well as traces of the iminochloride and starting material. Recrystallization of the more polar diastereomer from chloroform gave large crystals, mp 191°-192° C.:

To a 125 ml three-neck round bottomed flask equipped with septum and N₂ inlet were added 3-bromo-5-phenyl-2,3,4,5-tetrahydro-1H-(1)benzazepin-2-one (3.216 g, 10.17 mmoles) and 50 ml dry tetrahydrofuran (THF) under nitrogen. The reaction was cooled in a dry ice bath, and lithium bistrimethylsilyl amide (11.2 ml of 1M in THF) was added slowly. The mixture was stirred for 5 minutes. T-butyl iodoacetate (2.708 g, 11.19 mmoles)was then added. The bath was removed and 25 ml of dimethylsulfoxide (DMSO) was added at -20° C. After one hour at room temperature, an acidified aliquot showed only a trace of starting material by TLC (24:1, CH₂ Cl₂ :EtOAc). The reaction mixture was poured into ice water and ethyl acetate containing 25 ml of N HCl, stirred for 5 minutes, and separated. The ethyl acetate extraction was repeated and the combined extracts washed three times with water, dried with brine and sodium sulfate, and filtered and evaporated, yielding 4.9 g (>100%, still containing traces of solvent) crude product.

Similarly, the lactam was alkylated with N-tert-butyl iodoacetamide to yield N-t-Butyl-2-[3-bromo-2-oxo-5-phenyl-2,3,4,5,-tetrahydro-1H-(1)benzazepin-1-yl]-ethanoic acid amide.

C. N-tert-butyl-2-[3-azido-2-oxo-5-phenyl-2,3,4,5-tetrahydro-1H-(1)benzazepin-1-yl] ethanoic acid amide

To a 250 ml round-bottomed flask equipped with N₂ inlet were added N-tert-butyl-2-[3-bromo-2-oxo-5-phenyl-2,3,4,5-tetrahydro-1H-(1)benzazepin-1-yl] ethanoic acid amide, (8.317 g, 19.37 mmoles), 90 ml dimethylformamide (DMF), and sodium azide (5.25 g, 80 mmoles, under nitrogen), and the mixture was heated at 75° C. for 20 hours with stirring. The reaction mixture was then cooled and distributed between water and ethyl acetate, separated, and the aqueous phase was again extracted. The combined extracts were washed with water three times, with bicarbonate solution once, and then dried with brine and sodium sulfate and filtered and evaporated, leaving a gummy residue, 8.58 g (100%), containing some solvent.

¹ H-NMR (δ, CDCl₃): 1.48 (s, 9H), 2.88 (m, 2H), 4.52 (AB quartet, J_(AB) =17, Δ.sub.γ =138, 2H), 4.57 (m, 1H), 5.06 (m, 1H), 6.73 (d, 1H), 7.26 (m, 8H).

D. N-tert-butyl-2-[3-amino-2-oxo-5-phenyl-2,3,4,5-tetrahydro-1H-(1)benzazepin-1-yl] ethanoic acid amide

The crude product from the previous displacement reaction, N-tert-butyl-2-[3-azido-2-oxo-5-phenyl-2,3,4,5-tetrahydro-1H-(1)benzazepin-1-yl] ethanoic acid amide, (8.58 g, 19.37 mmoles), was dissolved in 75 ml methanol under nitrogen. The catalyst, 6 g of 5% Pd/C, 50% w/w, was added and the mixture was hydrogenated at 55 psi H₂ for 5 hours. The mixture was filtered through Celite® and the catalyst washed three times with methanol and the filtrate evaporated. TLC (24:1, methylene chloride: methanol, silica gel), showed less polar material and the product at R_(f) 0.25. The crude product taken up in ethyl acetate and extracted with acid. The acidic extract was back washed with ethyl acetate and then the aqueous fraction was taken with fresh ethyl acetate and the pH adjusted to 10.0. The organic fraction was then dried with brine and sodium sulfate, filtered and concentrated, yielding 1.832 g (25.8%) of the crystalline amine (mp 189°-192° C., one diastereomer). The mother liquor yielded 1.545 g (21.8%) of a foam upon stripping the solvent, which contained nearly a 1:1 mixture of the diastereomers.

EXAMPLE 60 Trans-1-(t-Butylacetamido)-3-(3-tolylureido)-5,7-diphenylhexahydroazepin-2-one A. 2,4-Diphenylcyclohexanone

Prepared in analogy with a method in Hussey, A. S. and Herr, R. R., J. Org. Chem., 24, 843, (1959). To a 500 mL round-bottomed flask equipped with N₂ inlet were added 37 g (0.212 mol) of 4-phenylcyclohexanone and 80 mL carbon tetrachloride. To the stirring solution was added dropwise over 30 minutes a solution of 20.5 mL (0.255 mol) sulfuryl chloride in 10 mL carbon tetrachloride. The reaction was stirred 14 hours at room temperature and poured into saturated aqueous sodium bicarbonate solution. The organic layer was separated, washed again with saturated aqueous sodium bicarbonate solution, dried over sodium sulfate, and evaporated to a yellow oil, 34.8 g (78%) which was used directly in the next step.

¹ H-NMR (δ, CDCl₃): (mixture of diastereomers) 1.9-3.6 (series of multiplets, 7H), 4.7 and 5.3 (multiplets, 1H), 7.2-7.4 (m, 5H).

The oil was dissolved in 400 mL benzene and added dropwise over 40 minutes to 83 mL (250 mmol) of a 3.0 M solution of phenylmagnesium bromide in ether, cooling so the temperature did not rise above 10° C. The reaction was then allowed to warm and heated to reflux for 14 hours. It was then cooled, quenched with aqueous ammonium chloride solution, then washed with water and brine, dried over sodium sulfate, and evaporated. The yield was 53.9 g (approximately theoretical), and the crude oil was used directly in the next step.

The above oil was dissolved in 200 mL methanol, and a solution of 18.6 g (0.267 mol) hydroxylamine hydrochloride and 37.2 mL (0.267 mol) triethylamine in 100 mL methanol added. The solution was decanted off the oily precipitate which separated and stirred at room temperature for 1.5 hours. The white precipitate was filtered and dried to give 13.6 g (31%) of a white solid, mp 214°-215° C.

C. 5,7-diphenylhexahydroazepin-2-one

To a 250 mL round-bottomed flask equipped with N₂ inlet were added 8.52 g (32.15 mmol) 2,4-diphenylcyclohexanone oxime and 110 mL pyridine. Once the solid had dissolved, the solution was cooled to 0° C., and 12.3 g (64.3 mmol) p-toluenesulfonyl chloride was added. The reaction was allowed to stir for 16 hours while the ice bath melted and the reaction warmed to room temperature. It was then poured into 300 mL 3N HCl, extracted into ethyl acetate, and the organic layer washed with additional HCl and brine, dried over sodium sulfate, and evaporated. The residue was chromatographed on silica gel using methanol/methylene chloride as eluant to afford 2.4 g (28%) of an oil which was crystallized from isopropanol to give mp 171°-173.5° C.
